Figure 6. Western blot analyses. Representative western blots and corresponding densitometric analyses of matrix metalloproteinase-2 (MMP-2; A; n=5), MMP-9 (B; n=5), cluster differentiation 44 (CD44s; C; n=5), and neurocan (D). Three days after retinal photocoagulation, expression of MMP-2, MMP-9, and CD44s were significantly higher, and expression of neurocan was significantly lower, compared with that of normal control retinas. * p<0.05, ** p<0.01.
